Really, my eyes just fall onto those telegraph poles. I think it would be a poorer picture without them - the sharpness of their shape gives the eye something to "settle" on.
I uses Paint shop Pro to crop the image, but any editing software should be able to take a part of an image and save it as a new image. I just kept it normal shape but just took the bottom left of your image. You (I think) just cut the top off? Its worh knowing that the human eye likes certain shapes and a 3:2 ratio is a good one to stick to
I think the sun and the telegraph poles give what one of your marsh scenes lacked - a point the eye settles on
Great photo mate
